I have a Delta 36-600 type 1 table saw and I can only get a couple uses out of a new set of brushes. The blade spins freely and when the saw runs it runs quite. I have never heard of this so any help in this matter will be greatly appreciated.

A ‘couple uses’??? I would open up the motor and see what things look like in there.. a set of brushes should last years and years under normal use, even longer for occasional weekend warrior type stuff. And that thing uses a universal screamer motor that is way loud, so your comment about it being quiet (‘quite’) is very surprising.

Cheers,
Brad

LOL.. might be worth a shot, but it’s an older saw with a universal motor, so they most likely are just going to suggest replacing the motor or taking it to a service center to have them look at it (and then paying them to replace the motor.. they won’t fix it, just replace it!!). Opening up the motor would be a good opportunity to also check the bearings. Those things (well, all I’ve taken apart) have a plastic housing that holds the rear bearing, and that is usually what fails first. Once opened up, it may turn out to be an easy fix (cleaning up the commutator), or it may be determined that it’s too far gone to try servicing. Just saying.

Cheers,
Brad

PS: One possibility is the wrong brushes have been installed.. ones that have beefier springs and are pushing too hard. About the only thing I can think of that would cause wear that fast other than a tore up commutator.

The surface the brushes are riding on is rough, grinding and burning the brushes up. They make a tool to clean it with but it’s used mostly in industrial motors that is large enough for it to be used on. You will probably have to tear the motor apart and clean it or take it to a motor shop and have the commutator turned.

Thanks y’all I took the motor out yesterday and sure enough the new brushes were over 3/4 gone so I have ordered some new brushes. I tried to break the motor down but did not have the right tool to pull the belt gear under the plastic cover. I looked as best as I could for anything obvious every thing turned smooth no noise bearing looked to be in good shape as best as I could tell without tearing the motor down anyway. I blew all the excess saw dust out and everything looks clean so I am at kind of at a stand still for now. Does anyone have advice as to how to get the pully off without breaking it ,it looks to be aluminum and alot of the parts for this old saw are obsolete.

Have your say...
